The year 1948 was an unusual time of great change in Chinese history. The sky, covered by dark clouds, echoed with thunder. The Central Plains battlefield was filled with smoke from the gunpowder. The liberation army began the prelude to the decisive battle between two fates. In the year 1948, the Liberation War finally transitioned from a strategic defense to a strategic counter-offensive. The main forces of the East China Field Army, personally commanded by General粟Yù, engaged in large-scale combat with Chiang Kai-shek's elite troops between Henan East and the Huai River region. With the cooperation of the Central Plains Field Army, the officers and soldiers fought bravely through days and nights under the scorching heat of summer. They successfully liberated Kaifeng, the first provincial capital inside the pass, and subsequently annihilated over ten thousand enemy troops in the Sui-Chi region, capturing the corps commander, Ou Shou-nian, alive.
